Methinks I would prefer a s/h Ovni to a new plastic Southerly.
You can't compare them in the same sentence.
Alubat Ovnis are centreboarders - the board is a flat, unprofiled slab of aluminium, with inefficient hydrodynamic lift, and which does not contribute to the righting moment (all ballast is within the hull). Southerlies are lifting keel boats, with a deep, profiled cast-iron keel that has good hydrodynamic lift properties, and which has sufficient weight to increase the AVS when down.
As a result, Ovnis are pretty hopeless going upwind, whereas Southerlies are amongst the best upwind cruising boats out there. Neither are great in light airs, but the Southerlies are significantly better than Ovnis.
In their defence, Ovnis are excellent for RTW and going well off the beaten track as they are fairly indestructible. Their AVS is not great, but they don't get rolled over in the southern oceans because with the centreboard up there is nothing for the boat to trip over - they just surf.
Southerlies are also pilot-saloon boats with forward view from the chart-table. Ovnis are like submarines once down below.
If you wanted an "Aluminium Southerly" you should look at the Hermine range by the French architect François Lucas - they have a deep profiled lifting keel in aluminium, ballasted with lead shot.
